Abstract

Inhibitors of BET bromodomains and compositions containing the same are disclosed. Methods of using the BET bromodomain inhibitors in the treatment of diseases and conditions wherein inhibition of BET bromodomain provides a benefit, like cancers, also are disclosed.

Description

FIELD OF THE INVENTION[0001]The present invention relates to BET bromodomain inhibitors and to therapeutic methods of treating conditions and diseases wherein inhibition of BET bromodomains provides a benefit.BACKGROUND OF THE INVENTION[0002]The genomes of eukaryotic organisms are highly organized within the nucleus of the cell. The long strands of duplex DNA are wrapped around an octamer of histone proteins (usually comprising two copies of histones H2A, H2B, H3, and H4) to form a nucleosome, which then is further compressed to form a highly condensed chromatin structure. A range of different condensation states are possible, and the tightness of this structure varies during the cell cycle. The chromatin structure plays a critical role in regulating gene transcription, which cannot occur efficiently from highly condensed chromatin. The chromatin structure is controlled by a series of post translational modifications to histone proteins, notably histones H3 and H4. These modificatio...
